Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic formulations are delivered to the nasal cavity for biomarker sampling, then the ability to target and retrieve biological materials is improved, but the device complexity increases due to the need for magnetic field manipulation and formulation composition
Solution Approach 1:
Magnetic particles serve as intermediaries between the external magnetic field and the biological material. These particles are incorporated into the formulation to enable magnetic manipulation, allowing remote control of formulation placement and retrieval without direct mechanical intervention in the nasal cavity
Solution Approach 2:
The formulation's magnetic properties are modified by incorporating magnetic particles, changing its physical parameters to enable response to external magnetic fields. This allows dynamic control of formulation behavior (movement, retention, retrieval) through magnetic field application without altering the biological sampling function
2Productivity
If magnetic formulations are used to enhance contact with targeted regions, then the collection efficiency of biological material is improved, but the ease of operation decreases due to the need for magnetic field control
Solution Approach 1:
Magnetic field manipulation replaces mechanical manipulation methods. Instead of requiring physical handling or surgical intervention to place and retrieve the formulation, external magnetic fields are used to control formulation movement and retention, simplifying the operational procedure despite adding magnetic control requirements
Solution Approach 2:
The magnetic formulation can be remotely positioned and retained at the target site without requiring manual adjustment or complex delivery mechanisms. The magnetic particles enable the formulation to self-position and self-retain under external magnetic field guidance, reducing the need for complex delivery device mechanics

AI summary
The present disclosure describes formulations, methods, and devices tor biomarker sampling and therapeutic delivery using magnetic formulations. When combined with the application of external magnetic fields, magnetic formulations move within the nasal cavity. Magnetic formulations provide benefits including the ability to: target or steer placement of the formulations via a magnetic field, enhance mixing of the formulation via a magnetic field, enhance biological material collection via antibody-coated magnetic beads, or enhance sample retrieval via a magnetic-tipped inserter. Example biological materials for collection include proteins, enzymes, neural stem cells, and other biomarkers.
